Rabbit anti-Human CBX2 Polyclonal Antibody

Uniprot Id

Q14781

Target Species

Human

Target Name

CBX2

Target Full Name

Chromobox protein homolog 2

Target Function

Component of a Polycomb group (PcG) multiprotein PRC1-like complex, a complex class required to maintain the transcriptionally repressive state of many genes, including Hox genes, throughout development. PcG PRC1 complex acts via chromatin remodeling and modification of histones; it mediates monoubiquitination of histone H2A 'Lys-119', rendering chromatin heritably changed in its expressibility. Binds to histone H3 trimethylated at 'Lys-9' (H3K9me3) or at 'Lys-27' (H3K27me3). Plays a role in the lineage differentiation of the germ layers in embryonic development. Involved in sexual development, acting as activator of NR5A1 expression.

Target Involvement

46,XY sex reversal 5 (SRXY5)

Target Subcellular Location

Nucleus. Chromosome.

Target Background

This gene encodes a component of the polycomb multiprotein complex, which is required to maintain the transcriptionally repressive state of many genes throughout development via chromatin remodeling and modification of histones. Disruption of this gene in mice results in male-to-female gonadal sex reversal. Mutations in this gene are also associated with gonadal dysgenesis in humans. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene.
